Idiopathic Pulmonary Arterial Hypertension

Definition

Primary pulmonary hypertension (PPH) is a rare disease. It is high blood pressure
in the blood vessels of the lungs.

A person with PPH has extra muscle in the walls of these blood vessels. That extra muscle makes it more difficult for blood to flow through them. As a result, the right side of the heart has to work harder to push blood to the lungs. This additional strain can eventually lead to heart failure.
